Supplemental tooth refers to an extra tooth resembling a tooth of the normal series of dentition. Supplemental teeth are less common than supernumerary teeth and are often overlooked because of their normal shape and size. Such teeth may cause many complications like displacement, delayed eruption, and root resorption of adjacent teeth, esthetic problems and even cyst formation. The present case series displays varying degree of impact of supplemental teeth on permanent dentition and thereby emphasizes upon the importance of early diagnosis and treatment planning. A rare case of supplemental maxillary lateral incisor showing an unusual talon cusp is also presented.
